The AYA01B05-L is a 3-watt isolated DC-DC converter from Artesyn's AYA series, designed for low-power applications in data communication, telecommunications, computer peripherals, industrial automation, and mobile battery-powered systems. It accepts an input voltage range of 4.5–10 Vdc and delivers a regulated 12 V output at 0.25 A with 85% efficiency. The converter features I/O isolation of 1500 Vdc, ultra-compact DIP packaging (14 × 14 × 8.0 mm), and operates reliably across -40°C to +85°C with a wide 2:1 input range. Output specifications include ±1.5% voltage tolerance, ±0.2% line regulation, 1.0% load regulation, and 70 mV noise/ripple, with continuous short-circuit protection and automatic recovery. This combination of isolation, efficiency, and compact form factor makes it ideal for space-constrained embedded systems requiring galvanic isolation and stable power delivery.
